AI Technical Summary

Technical Problem

In existing resistance welding clamps, the electrodes are exposed to a spatter environment during the welding process, which causes impurities to adhere rapidly, resulting in problems such as decreased electrode flatness, increased contact resistance, welding defects, and shortened service life.

Method used

A high-precision robotic welding clamp was designed, equipped with a cleaning brush and a water spray system. The cleaning brush scrapes and the water spray sprays cleaning fluid to pre-clean the electrodes and prevent the accumulation of impurities. The design of the guide plate and fan blades enables the switching between large-area and small-area cleaning.

Benefits of technology

It effectively extends the service life of the electrodes, reduces welding defects, improves welding quality and efficiency, and delays the electrode grinding and maintenance cycle.

Abstract

This invention relates to the field of metal welding technology, specifically a high-precision robotic welding clamp, comprising a metal welding device body, a first fixed frame, and a lower straight-arm welding clamp fixedly mounted on the metal welding device body. A lower straight rod electrode is fixedly mounted at the end of the lower straight-arm welding clamp, and a second fixed frame is fixedly connected to the outer wall of the lower straight-arm welding clamp. A high-pressure conductive cleaning fluid pipeline is connected to a water supply pipe, which delivers the fluid to a second rotating ring and then to a storage ring. When the storage ring is full of cleaning fluid, the water pressure causes the cleaning fluid to be delivered into multiple water inlets. After entering the spray pipe, the cleaning fluid rushes towards the fan blades, causing the fan blades to start rotating. This causes multiple guide vanes to rotate outward and open. The guide vanes rotate with the fourth hinge shaft and cause the torsion spring to store force. The opened guide vanes guide the direction of the cleaning fluid sprayed from the spray pipe, resulting in a larger spraying range.
